New to Knives 8/2/04 I'm new on the knife fish thing so
you might need to help me. I don't have any current problems
but, I want to know if three glass knifefish in a 55
gallon tank is ok. < These fish have weak electronic organs and when
they are kept together they seem to always be bickering amongst
themselves. They don't do any real harm to each other so if you
have plenty of areas to hide then they should get along fine.>
Males grow about 18" and females 11". A fish manual says
1" per gallon that would be 54" with three MALES.
Here's the question. How do you tell male from female when they are
the same size. < The books all say that the males get to be the
larger fish. They are somewhat transparent so look for
differences in the body itself. You may not see any until they get
close to adult.-Chuck> They are about 4".((I have other fish in
there already.)) Please Help If Possible. Thanks.
